Title: Inter-picture correspondence detecting method and device therefor
Inventor: EITO MINORU
IPC: H04N19/51
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To attain mapping parameter estimation by using luminance error miniaturization as a reference even when large moving amounts are present between the corresponding positions of different projected images used for a picture encoding and decoding device, stereo picture measurement, and wide visual field picture generation. SOLUTION: This method is constituted of the following three basic processings. A block matching-based error arithmetic processing 101 operates block matching for minimizing the sum of absolute difference value of a luminance error from among reference picture elements for a block constituted to 16×16 picture elements in a reference picture. Then, a secondary error function approximation processing 102 by a differentiation operator performs secondary error function approximation by assuming that the block matching result forms a bowl-shaped curve surface. Then, a non-linear repeated minimization processing 103 for a plane perspective mapping parameter calculates the sum of a secondary error function for a whole screen by the successive repeated processing of an improved Newton method for the parameter of the plane perspective mapping.

Abstract: PURPOSE:To prevent deterioration of recording quality to be caused by irregularities in rotation to be encountered when the driving condition is changed, by a method wherein a motor is so controlled as to be driven under the same driving condition as that during recording operation, beginning two or more lines in advance of the record-start position. CONSTITUTION:When a recording is started after a recording paper is set in a printer, a recording paper 2 is automatically wound around a platen 1. A motor 24 is driven by an constant-speed pulse, asynchronous to a video signal 6, so that the platen 1 is fed toward the record-start position at constant-speed. When the recording paper 2 faces a recording head 3 at a position thereon which is two or more lines up to record-start position, the constant-speed feed is switched to the intermittent feed. Upon completion of the intermittent feed of the predetermined number of lines, a control signal 20 from a line signal generating circuit 32 goes to an H-level, which permits the operation of an A/D converter 30, and the video signal 6 is output to a head drive circuit 11 as a density signal for one-line 10 and therein converted in a recording signal 12 which enables a recording head 3 to perform recording. In this manner, a printing record of good image quality can be obtained by electrical control processing alone.
